Bitcoin trading mainstream in China, however Nigeria is not among the top 10 countries trading Bitcoin , could it be that Nigeria government have not legalize Bitcoin?why is China among the top 10, but Nigeria isn't? That source is definitely wrong.
Where did you read that Nigeria is not part of the first 10 in P2P trading?
AFAIK Nigeria doesn't ban Bitcoin but the central Bank on Nigeria could freeze your account if they detect the funds came from Bitcoin, high inflation rate, still a third world countries means not prosperous yet. That's why the trading volume of Nigeria can't be compared to first or second world countries, however there's an article said Nigeria become the top 2nd Bitcoin trading volume but keep in mind it's only on Paxful [1] not an entire exchanges.
I thought the data was both on Paxful and Localbitcoins, correct me if wrong. Nigerians have significantly also making use of Binance recently.
You are right, the CBN banned bitcoin, but the use of P2P is effective, no account freeze if P2P is used, while direct bitcoin or crypto to bank transactions have been blocked, so nothing like freezing of account.
I do not think this bring the perfect picture of crypto trading volume per country, why also
PPP was used for the three calculation. Check the P2P, how is Togo ranked 2nd while Kenya ranked 1st? How is that possible.
